You know it's a sin to tell a lie ... still you keep 
saying 'I love you' ...
It may be true, I wish I knew ... but I'm giving fair 
warning to you ...

Be sure it's true when you say, 'I love you'
It's a sin to tell a lie
Millions of hearts have been broken
Just because these words were spoken

I love you, yes, I do, I love you
If you break my heart I'll die
So be sure that it's true when you say, 'I love you'
It's a sin to tell a lie

I love you, yes, I do, I love you
If you break my heart I'll die
So be sure that it's true when you say, 'I love you'
It's a sin to tell a lie
It's a sin to tell a lie
